WARNING: If you don't like having to register with publisher-specific on-line services to play individual (or publisher-specific groups of) games... DON'T BUY THIS GAME.
This game requires registration and login into Ubisoft's unique/ publisher-specific on-line gaming service, UPlay, in order to play this game. To the best of my present knowledge, login into this service is mandatory each/ every time you play the game (it cannot be bypassed).
Personally... I HATE publisher-specific on-line gaming services (MMO's excepted). (I don't count steam into this category, as they have opened their platform to various publishers for authentication and other purposes.) I refuse to create seperate accounts with EA, Microsoft, Ubisoft, etc. (e.g., all the big publishers) so that they can track my activity, on a granular level, accross their portfolio of games (among other things). I also don't want the (further) hassle of having to maintain seperate user identities just to *play games*, like I have to already do to manage the remainder of my on-line life.
As a matter of principle... I also consider it ridiculous that I should have to log into a publisher-specific service to play what would otherwise be an off-line single-player gaming experience, with *zero* content otherwise hosted "in the cloud". (e.g., all game saves would be to local media.)
I can't give a critique on the content of the game itself, as I have been unable to play it, as I have refused to create an account on uplay.
I now have to uninstall the game that I paid good money for... Without reasonable hope of ever being able to play it. To say that I'm pi$$ed off at the moment is a monumental understatement. (Shakes fist at heavens whilst cursing Ubisoft.)
